Summary: 
A novel buffer-based switched-capacitor (SC) integrator integrable by a method of reducing capacitance ratio is presented. By this method, high Q sc filter can be made by realizable capacitance ratio on CMOS process. The proposed integrator can also be operated over wide frequency range because it uses a unity gain buffer (UGB).
